Electrical Power & Heating Effect

In producing chlorine by electrolysis 100 kW100\text{ kW} power at 125 V125\text{ V} is being consumed. How much chlorine per minute is liberated (E.C.E. of chlorine is 0.367×10−6 kg/C0.367 \times 10^{-6}\text{ kg/C})

Show answer and solution

Answer: (d)

  1. I=PV=100000125=800I = \frac{P}{V} = \frac{100000}{125} = 800 A.
  2. Charge per minute q=800×60=48000q = 800 \times 60 = 48000 C.
  3. m=Zq=0.367×10−6×48000≈17.61×10−3m = Zq = 0.367 \times 10^{-6} \times 48000 \approx 17.61 \times 10^{-3} kg.
  4. So the answer is (d).
